Andrey Rublev has immense potential and he's shown it throughout the 2019 season. The world No. 31 didn't capture an ATP title this season, but he did reach the deeper rounds in plenty of tournaments after coming back from a back injury.
On Tuesday, the Russian defeated Alexander Bublik, 6-1, 3-6, 6-4, in his opening round in Moscow. This win marked Rublev's first victory in his home country, and ended a seven year drought, having gone 0-6 in appearances since 2013.
He's had better luck at the other ATP stop in Russia in St. Petersburg, where he's 3-4 and reached the quarterfinals in September.
Rublev was all smiles following the match and thanked his home-country for their support via Twitter.
